Although the story about Stephen Stills auditioning for the Monkees is apparently at least somewhat apocryphal—Stills says that he only wanted to sell the group’s management some of his songs—he did play guitar on one Monkee’s song, the Head soundtrack’s “Long Title: Do I Have to Do This All Over Again?”

Stills longtime musical partner Neil Young, however, was a Monkee himself—well, so to speak—for four numbers.

Young plays guitar on Head‘s gorgeous “As We Go Along” and he also played on a few tracks recorded by Davy Jones in a session produced just days after he left The Buffalo Springfield: The lovely, but slight “Smile”; a backing track for the never completed “That’s What It’s Like Loving You” and the simply incredible “You And I,” which appeared on the underrated Instant Replay album in 1969.

This features some of the best, most blistering Neil Young guitar work like… ever. Such a great pop song. Why was this not a massive, massive hit?
